摘要
A dynamically screened three-Coulomb-wave （DS3C） method is applied to study the single ionization of magnesium by electron impact. Triple differential cross sections （TDCS） are calculated in doubly symmetric geometry at incident energies of 13.65, 17.65, 22.65, 27.65, 37.65, 47.65, 57.65, and 67.65 eV. Comparisons are made with experimental data and theoretical predictions from a three-Coulomb-wave function （3C） approach and distorted-wave Born approximation （DWBA）. The overall agreement between the predictions of the DS3C model and the DWBA approach with the experimen- tal data is satisfactory.
